To all whom itmay concem:

Be it known that I, BnAnFonoWnBsrnn,

. of Newark, Essex county, New Jersey, have I nvented certain new and useful Improvements in Perforators, of whichthe following is a specification...

My inventionrelates principally. to perforations for punching paper and the like for filing purposes. It has for its object to provide a perf-orator of greater power, permanence, and simplicity of structure.

In the drawings similar characters of reference refer to similar parts inthe different views. j a 1 is t Figure 1; is a general perspective view of an embodiment of my invention. Fig; 2is a vertical cross-section of the upper part of the device on the line X -X of Fig.1. Fig. 3 is a vertical cross section and elevation on the line Y Y. of Fig. 1. a

In my invention I use preferably body casting 1, provided with bearing portions for the drive-pins or punching pins 4:, with bearings for the drive shaft 2, with a centering lug 11, with throats 12 for receiving the paper, and with a discharge opening 13 in its upper portion for removing punchings. The throats 12 cross transversely the openings in which the punching pins 4 work. To the bottom of the body member 1 is fixed a plate of metal, wood, binders board or the like, preferably flush with the bottom of the member 1 and provided with a soft covering 14 extending out under the bottom edges of the member 1. Thus this plate and covering 14 contain. the punchings and at the Same time provide a soft bottom that will not scratch wooden surfaces.

The body member 1 is provided with extensions 1 which serve as bearings for the drive shaft 2. The bearing portions of the drive shaft 2 consist of integral pin extensions 3 at each end, the axes of said pin extensions being eccentric of the main axis of the shaft. hen the handle 10 is in its position of rest several degrees back of perpendicular, the main axis of the shaft 2 is above the axes of the pins 3.. The shaft 2 is placed above the pins 4 so that rotation by the handle 10 will cause said shafts to bear against the tops of pins 4 and drive them down by direct contact.

To make it possible to get the great etability and permanence resulting from an in the upright 14. X the punching pins withthe drive shaft and to return positively the punching pins .after they have been driven ,fdownpl providela cross-pin 9 through the tegral ,bodyrastinggthe opening in one of the uprights 1. is slightly larger in diameter {than the shaft2. NVhen the shaftf2 is in positiomthis openingis filled by the bushi1ig7, which isheld in fixedrelation with .saidshaft2 by riveting or otherwise fastenmg the end of pin 3 over the outer surface of bushing 7,. This fixed relation ofshaft 2 and bushing 7. holds shaft 2 positively with p 111 the body member 1 between the uprights l as shown in Fig. 3, a substantial partof the mainend surface of the shaft"2 always resting against part of the innersurface of To connect holes Sof one or more punching pins l. The holes ,8 are substantially larger than tl1e, cross-pin 9 to allowa lost-motion connection between the drive shaft 2 and punching pins 4, and to allow the punching pins 4: to hang normally free and clear of the surface of the shaft 2 until pushed up against same by working contact below. I connect the cross-pin 9 with the shaft 2 by the collars 6 which ride snugly on the shaft 2 and move up and down as the axis of the shaft 2 moves up and down by eccentric rotation in the uprights 1'.

To maintain a general state of buoyancy and tension in the drive mechanism, I place the coil springs 5 around each punching pin 4.- between an upper surface of the body member 1 and the cross-pins 9. This tends to raise the collars 6 more snugly up against the drive shaft 2 at all times. It is evident that the tension of the springs 5 through the coaction of the cross pins 9 and collars 6 tend to raise the drive shaft 2 so that its main axis is directly above the axes of the pins 3.

The lost motion connection between the drive shaft 2 and the pins 1 is important in enabling thecollars to ride freely on the said shaft. By this lost-motion connection the drive shaft does not come into working relation with the tops of the punching pins until both are in motion downward.

I do not limit myself in any way further than is indicated in the claims which follow.

I claim:

1.. In a perforator, in combination: a body member, a drive shaft provided with end extensions eccentrically placed with respect to the axis of said shaft, and a bearing mem-' her; said drive shaftholding said bearing member Within) said body, member; said bearing member holding said drive shaft positively in driving position and positively Within said body member.

' 2; In a -perforator, the combination of-a perforating pin, a drive shaft rotatin across the top of said pin and se arate therefrom in its normal position w en not driving said pin, said shaft during a portion of its rotation contacting with the top of said .pin to drive the latter, means associated with the shaft for positively returning said perforating pinto its initial position after performing its function of pertrically across the top of said pin and driving in direct contact with same, and acollar riding snugly on said shaft, provided with a lost motion comiection with said pin, and

' adapted to reciprocate said pin after driving.
